Description
Изобретение относитс к испыта-. тельной технике, а именно, к устройствам дл определени прочности аадгезионных соединений.The invention relates to a test. technical equipment, namely, to devices for determining the strength of adhesive joints.
Известно устройство дл определени прочности адгезионного соединени , содержащее подложку с коническим отверстием и установленный заподлицо.в бтверстии подложки штиф, обща поверхность которых предназначена дл нанесени адгезива A device for determining the strength of an adhesive joint is known, which contains a substrate with a conical opening and is installed flush. In the opening of the substrate, a pin, the total surface of which is intended to apply adhesive
Недостатком известного устройства вл етс низка точность определени прочности адгезионного .coejS Heни при испытании, так как устройство не позвол ет учитывать действие касательных напр жений в исследуемом соединении.A disadvantage of the known device is the low accuracy of the determination of the adhesion strength of the .coejS HeNi during testing, since the device does not allow for the effect of tangential stresses in the compound under test to be taken into account.
Известно устройство дл определени прочности адгезионного соединени , содержащее коническую подложку и установленную на ней обойму с коническим отверстием, зазор между которыми предназначен дл заполнени адгезивом t Недостатком устройства вл етс больша трудоемкость, испытани при изменении- углов конусности подложек, так как необходимо кгокдый раз изготавливать специальную обойму с угломA device is known for determining the strength of an adhesive joint containing a conical substrate and a holder mounted thereon with a conical opening, the gap between which is intended to be filled with adhesive. The disadvantage of the device is great labor intensity, testing with changing the angles of tapering of the substrates, since it is necessary to make special clip with angle
конусности, соответствующим углу конусности подложки, и при этом обеспечивать соответствующий зазор между подложкой и обоймой.taper, corresponding to the angle of the taper of the substrate, and at the same time provide an appropriate gap between the substrate and the yoke.
Цель изобретени - снижение трудоемкости при испытании с учетом изменени углов конусности подложек.The purpose of the invention is to reduce the labor intensity during the tests, taking into account the change in the taper angles of the substrates.
Дл достижени поставленной цели обойма выполнена цилйндрической и To achieve the goal, the yoke is made cylindrical and
10 установлена на подложке у ее основани , а устройство снабжено стаканом, размещенным внутри и на пЬдпожке .10 is mounted on a substrate at its base, and the device is provided with a glass disposed inside and on the pad.
На фиг.1 изображено устройство пе5 ред испытанием; на фиг.2 - то же в момент испытани ; на фиг.З - схема распределени сил на границе раздела адгезив-подложка.Figure 1 shows the device before testing; 2 is the same at the time of the test; FIG. 3 is a diagram of the distribution of forces at the interface of the adhesive substrate.
J,. Устройство содержит коническую подложку 1, цилиндрическую обойму 2, установленную на подложке 1 у ее основани , стакан 3, внешний диаметр которого меньше внутреннего диаметра обоймы 2, установленный на подложке 1 внутри обоймы 2, накидные гайки 4 и 5 с отверсти ми в донных част х и захваты 6 и 7 с полусферическими головками. В боковой стенке обоймы 2 выполнено отверстие 8 дл J. The device comprises a conical substrate 1, a cylindrical holder 2 mounted on the substrate 1 at its base, a cup 3 whose outer diameter is less than the internal diameter of the holder 2 mounted on the substrate 1 inside the holder 2, cap nuts 4 and 5 with holes in the bottom parts and grips 6 and 7 with hemispherical heads. In the side wall of the yoke 2 is made a hole 8 for
